Tidewater Fuel Line Leak, Pasco

Ecology visited the site May 20, 2024, and inspected the groundwater monitoring wells. We made some recommendations for well repairs and improvements. The cleanup still protects people and the environment. Ecology will also work with Tidewater to file an environmental covenant on the property to warn any future owners of the remaining contamination.
